Size Does Matter. Or does it? This theory has been continually disproved over the years through technical advances. There could not be a better example than Nissan's new motor, a motor only weighing in at 88 pounds. The Nissan DIG-T R is a turbocharged, 1.5 Litre, gas powered powerhouse.
Revving at 7,500 rpm, it produces 400hp (298kw) and 380nm of torque. These are impressive figures- especially due to the fact that this engine, with dimensions of 500cm x 400x 200, is small enough to be taken as carry on luggage on a flight. The power-to-weight ratio for the engine works out to 10 bhp per kilo. This ratio is better than the new engines to be used in the FIA Formula 1 world Championship this year. This power is achieved through the use of a variable compression technology that allows the engine to choose the optimal compression ratio for combustion at any moment. This technology gives the engine the performance of a turbo-charged gasoline engine while also allowing it to match the power and efficiency of the most modern diesel and hybrid power trains. This engine is to be used to power Nissan's ZEOD RC at Le mans this year.
The ZEOD RC will complete the first lap using the power of its electric power plant. After this, the DIG-T R will take over. Nissan has set a new standard in efficiency and power with this engine. It is all you could which for in an engine- great efficiency without sacrificing power.
